whats the best motor oil for an lt1?
#46
oil pressure
My lt1 holds anywhere from 30-70 lbs of pressure. I run Mobil 10-30. It has developed a sort of knock when you first fire it up. Is that because its like 30 outside or should i start to worry?

mine knock for 5 to 10sec and goes away - i use 10-40 i live in a country that reach 40 degree in the summer ( 104 f ) and winter 5 to 10 c ( 40 - 50f ) so i use alll the time 10-40 semi synthetic api - with no issue for the pressure on cold go up 60 iddle at 20 in hot weather will fire up at 60 and iddle less then 20 ( maybe 15 )
